Difference Between IEnumerable And IEnumerator

Difference between IEnumerable and IEnumerator with example.

Difference between IEnumerable and IEnumerator.

1. IEnumerable uses IEnumerator internally.
2. IEnumerable doesn’t know which item/object is executing.
3. IEnumerator knows the current position of item/object.
4. IEnumerable doesn't know the current position of item/object
5. IEnumerable has one method, GetEnumerator ()

// Difference between IEnumerable and IEnumerator.
public class Program {
    public static void Main(string[] args) {
        IEnumerable_Example();
